£17million Strathaven substation upgrade to benefit residents in South Lanarkshire and beyond


We have successfully completed a £17million upgrade to the Strathaven 275kV substation near Hamilton in South Lanarkshire, a part of our extensive investment in futureproofing the reliable and safe supply of electricity for customers.

The completion of the works follows a three-year modernisation project that will benefit not only customers in the local area, but right across central and southern Scotland.

The works involved the installation of new equipment, including the construction of 10 switchgear bays that will support the long-term reliability of the network. The upgrade was carried out in live substation conditions by a range of specialist contractors, each phase managed carefully to maximise the residual reliability of the network for customers during the project works.   

This vital project went without a hitch, with the new switchgear bays installed ahead of schedule – a significant achievement given the impact of Covid-19 restrictions.

Pearse Murray, SP Transmission Director at SP Energy Networks said: “We’re committed to futureproofing the network for our customers to provide a reliable, efficient and safe electricity supply and this project is part of an extensive investment plan to achieve exactly that. As demand for electricity increases and we transition to a greener society and decarbonise how we travel and how we heat our homes, it’s important that our network can support these necessary changes. Investment like the Strathaven substation upgrade is vital so we can continue to make that happen.

“In this year of COP 26 in Glasgow, we’re proud to be delivering projects that support plans for a low carbon Scotland. The modernisation of our transmission network is key to enabling the country’s ambitious Net Zero emissions targets, which places an ever increasing reliance on electrical infrastructure and will help us all achieve a cleaner and better future, quicker.”

This upgrade project is part of a wider investment plan which has seen over £2 Billion invested over the past eight years to modernise and grow the transmission network across Central and Southern Scotland.
